热熔压敏胶的合成与性能研究-学位论文.doc

北京理工大学珠海学院2011届本科生毕业论文PAGEIV毕业论文热熔压敏胶的合成与性能研究摘要热熔压敏胶是以热塑性聚合物为主的胶黏剂，它兼有热熔和压敏双重特性，涂胶时必须将胶加热熔化（一般为150―200℃），在熔融状态下进行涂抹，冷却中固化，固化后施加轻度指压就能起到粘接作用。它的应用范围很广，目前已用于尿布、妇女用品、双面胶带、标签、包装、医疗卫生、书籍装订、表面保护膜、木材加工、壁纸及制鞋、标签纸及地毯粘接等方面，也可制作纸基或布基的胶黏带，其中，包装用HMPSA消费量最大，几乎占总量的一半，是无溶剂型压敏胶黏剂中发展较快的几个品种之一。本文针对热熔压敏胶的初黏力、持黏力、剥离强度三大压敏性能进行研究，目的是设计研究出一种具有一定初黏力，一定剥离强度，较强持黏力的热熔压敏胶，在这个基础上，最好能具有耐高温性能。关键词：热熔胶压敏胶持粘力软化点剥离强度Synthesisandpropertiesofhotmeltpressure-sensitiveadhesiveresearchAbstractHotmeltpressure-sensitiveadhesiveisathermoplasticpolymer-basedadhesive.Ithasbothhotmeltandpressure-sensitivedoublefeature.itmustbeheatedtomeltwhengluing(typically150-200℃).Tosmearoverinthemoltenstate，Coolinginthesolidification,Lightfingerpressureappliedaftercuringcanplayaroleofadhesive.Itiswidelyusedinmanyarea,suchasithasbeenusedindiapers,women'sproducts,double-sidedadhesivetape,labels,packaging,health,bookbinding,surfaceprotectionfilm,woodprocessing,wallpaperandfootwear,andcarpetadhesivelabelpaper,andsoon.Itcanalsobemadeofpaper-basedorclothadhesivetape.Ofwhichthelargestconsumerpackagingishotmeltpressure-sensitiveadhesive,accountingforalmosthalfofthetotal.Pressure-sensitiveadhesiveissolvent-freehotmeltpressure-sensitiveadhesiverapiddevelopmentoneofseveralspeciesInthisarticle,IresearchforthebeginningAdhesion,holdingadhesionandthepeelstrengthofthehotmeltpressure-sensitiveadhesive(HMPSA).MyobjectiveistodesigndevelopedanewHMPSA.IthasthebeginningAdhesion,theholdingadhesionandastronglypeelstrength.Onthisbasis,itisbettertohavegoodhightemperatureresistantperformance.KeyWords：HotMeltPressure-sensitiveAdhesiveHoldingAdhesionSofteningpointPeelstrength目录TOC\o"1-2"\h\z\uHYPERLINK\l"_Toc292196969"摘要PAGEREF_Toc292196969\hIHYPERLINK\l"_Toc292196970"AbstractPAGEREF_Toc292196970\hIIHYPERLINK\l"_Toc292196971"1.前言PAGEREF_Toc292196971\h1HYPERLINK\l"_Toc292196972"2.热熔压敏胶的简介PAGEREF_Toc292196972\h3HYPERLINK\l"_Toc292196973"2.1概述PAGEREF_Toc292196973\h3HYPERLINK\l"_Toc292196974"2.2性能及其影响因素PAGEREF_Toc
